We propose a new interpretation of objective probability in statistical physics based on physical computational complexity. This notion applies to a single physical system (be it an experimental set-up in the lab, or a subsystem of the universe), and quantifies (1) the difficulty to realize a physical state given another, (2) the ‘distance’ (in terms of physical resources) between a physical state and another, and (3) the size of the set of time-complexity functions that are compatible with the physical resources required to reach a physical state from another. This view (a) exorcises ‘ignorance’ from statistical physics, and (b) underlies a new interpretation to non-relativistic quantum mechanics.

Keywords: Probabilità, ignoranza, oggettività, soggettività, meccanica statistica, meccanica quantistica, complessità
